HEATING OR COOLING APPARATUS Specification of Letters Iatent.Application filed July 1, 1907. Serial No. 381,754.

T o all 'whom it may concern:

Be it known that l, JULES HEIZMANN, a subject of the German Emperor, andresiding at Strassburg, Alsace, German Empire,

. have invented certain new and useful lmprovements in Heating orCooling Apparatus, of which the following is a speci'lication.

My invention relates to improvements in devices for heating, drying,superheating,

condensing, cooling or the like.

The object of the invention is to provide a construction in which, forminimum bulk, there is a maximum effective heating or cooling surfacepresented, this object being secured by providing specially formedchambers for the passage of the fluid to be heated or cooled. Eachapparatus may be used as a separate device, or in an assemblage, as insuperheaters, coolers, or the like.

My invention is illustrated in the accompanying drawing, in which-Figure l is an elevation of one l'orm olI the apparatus. Fig. 2 is asectional view, the upper part heilig a section on the line AMB :5 ofFig. l while the lower part shows a modiiication. Fig. 3 is a verticalsection through a second modification. Fig. 4 is an elevation of anapparatus having adouble body.

Fig. 5 is a section on the line (l-D ol" Fig. 4l. Fig. 6 is an elevationand part section of a Jfurther modification. Fig. 7 is a section on theline E-F of Fig. 6. .Figs S-l2 illustrate various methods of assemblingthe apparatuses.

The body a of the apparatus may be cast,

welded, or riveted. ,lts side walls l) are sinuous and together withtheV Vfront and back walls c inclose a chamber d having an inlet and anoutlet @,f. The walls c are stayed by 'LO means of short pipes g or thelike, cast with the body or secured in place in any suitable manner.They may, if desired, be conical (Fig. 2), and constitute passagesthrough the These pipes g may body of the apparatus. be replaced bysolid members, as shown in Fig. 3. A

The fluid passing through the body a contacts with the sinuous walls l)and also with the pipes g, so that it is constantly being separated intocurrents and thoroughly mixed. The direction of motion of the fluid maypenetrate the chamber at any desired angle.

The body a is so set up that the heating or cooling medium surroundingit will contact very large.

with the side walls l) and the walls of the pipes g. In this manner theell'ective heating or cooling surface presented is relatively The V[luidl'lowing through the chamber d is kept in constant motion, in order thatall solid portions may be contacted with as often as possible.

Such a device may be placed in any desired position and any number ofsuch devices may be assembled in any suitable manner, whether parallelwith each other or in line, as shown for instance in Figs. S, 10 and 11.These ligures are diagrammatical and show respectively in Fig. S, anumber of devices constructed as in Fig. l, set side by side 7e theVlluid llowing alternately upward and downward through adjacent chambersuntil the end et the series is reached, in Fig. l0 two upper pairsv ollchambers constructed as in Fig. l and a lower chamber constructed as inFig. +L, the lluid 'passing down through the right hand chambers ol thetwo pairs, then down and up through the lower chamber, and linally upthrough the lelt hand chambers of the two pairs and out; and in Fig. .llSe three series o'lv chambers as in Fig. 1, each series comprising l'ourchambers, and the three series beiiig arranged one series above theother, the [luid passing down through the right hand chambers o'l allthe series, then up through the adjacent chambers of all the series,then down again through the next line ol chambers, and inally up throughthe left hand line of chambers of the three series, and out.

The device may have a double body a, such, for instance as shown in Fig.4. The central partition 71. compels the lluid to flow through theentire apparatus. F 9 illustrates an assemblage ol such double devices,in which the [luid passes alternately up and down through the successiveseries. l

Figs. (3 and 7 show-another modification il: placed in vertical positionand assembled in a row, the connected inlets and outlets e, j, wouldconstitute lcet. The heat radiating or absorbing l'luid medium wouldcontact with the outer walls l) and ass through the passages g andcentral eye i. The devices might be inclined to one another, such forinstance as shown in Fig. 12. The medium would here flow through theangularly arranged spaces 7c and pass through the passages g, asindicated by the arrows.

ln Figs. S to l2 ol the drawing, which, as

hereinbefore stated, are diagrammatical, and which, as will be readilyobserved, are drawn to a very small scale, no attempt has been made toshow the specific construction of each apparatus comprised inthe severalarrangements, such gures being intended solely to illustrate the mannerin which series of the devices may be arranged to cooperate with eachother, and to show how the Huid passing through one body may be causedto pass through others arranged adjacent thereto.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is r` 1. A heating and cooling devicecomprising two parallel iiat plates, stays connecting them andmaintaining them apart forming a space between them, edgeplates ofcorrugated form secured between the parallel plates and formingboundaries for the inclosed space, and an inlet and outlet for saidinclosed space, said stays being arranged in parallelism with thecorrugated edge plates and in such relation therewith and with eachother as to cause the medium passing through the inclosed space totravel in sinuous paths and to contact with said stays and corrugatededge plates, substantially as and for the purpose specified.

2. A heating and cooling device comprising two parallel flat plates,tubular stays connecting them and maintaining them apart forming a spacebetween them, edge plates of corrugated form secured between theparallel plates and forming boundaries for the inclosed space and aninlet and outlet for said inclosed space, said tubular stays beingarranged in parallelism with the corrugated seais@ ledge plates and insuch relation therewith and with each other as to cause the mediumpassing through the inclosed space to travel in sinuous paths and tocontact with said stays and corrugated edge plates, substantially as andfor the purpose specified.

3. A heating and coohng device comprising two parallel plates, staysconnecting them and maintaining them alpart forming a space betweenthem, edge p ates of corrugated orm secured between the pla-tes andforming boundaries for the inclosed space, inlet and outlet pipes sideby side communicating with the inclosed space, and a partition betweenthe inlet and outlet pipes secured between the parallel plates and projecting into the inclosed space, substantially as and for the purposesspecified.

4. A heating and cooling device comprising two parallel platessubstantially circular in form, tubular stays connecting them andmaintaining them apart forming a space between them, corrugated platessecured between the peripheral edges of the parallel plates formingboundaries for the inclosed space, a radial partition extending into theinclosed space and terminating in the center of the inclosed space, andtwo substantially parallel passages on opposite sides of the radialpartition forming inlet and outlet to the inclosed space, substantiallyas and for the purposes specified.

In testimony whereof l affix my signature, in presence of twosubscribing witnesses.
